Genetics Human behavior can be affected in many ways, one of which is genetics. Everyone has different traits such as intelligence and shyness which they inherit through heredity. These traits impact human behavior and there are indications that behavior is affected by genetics. First, behavior can be different in different species. People behave differently from how a chickadee behaves for example. Second, behavior can be reproduced in consecutive generations of humans. In each generation of people there will be similar behaviors that occur. Third, biological structures can be alternated resulting in behavior changes. For example, if one develops a brain injury, one can change from behaving politely to being aggressive. Another way behavior can be affected is by behaviors that are brought up in families. For example, certain behaviors that can occur from a mental illness that runs in the family. Fourth, evolutionary history of genetics has a big impact on behavior. All species have DNA which can bind them all together. Geneticists are now able to introduce or exclude specific genes, resulting in different traits and behaviors arising from those traits. One gene does not create behavior. Behaviors result from a combination of genes, and these genes can be affected by different factors. Factors such as genes and environment are included in the growth of any trait. Genes can be manipulated and modified and the environment can increase certain outcomes of genes. Understanding genetics in relation to behavior is difficult and there are many things still being studied about this. source wiki.
